The invention discloses a train stability evaluation method based on recurrence plot analysis. The method comprises the following steps of respectively acquiring vibration acceleration signal sequences of M sampling periods of a left front wheel, a right front wheel, a left rear wheel and a right rear wheel of a train bogie; regarding a vibration acceleration signal sequence of a left front wheel as a state track of vibration acceleration in a three-dimensional phase space, and constructing M recurrence plots corresponding to M sampling periods of the left front wheel according to comparison of the distance between vibration acceleration vectors corresponding to any two sampling times ti and tj in the phase space and a critical distance; and according to the change characteristic values of the recurrence plots of any two adjacent sampling periods, judging the running state of the left front wheel, acquiring the running states of other wheels of the bogie by analogy, and then determining the running state of the train. According to the invention, the stability of the train is judged by constructing the recurrence plot, and more comprehensive and more accurate control over the running condition of the train is achieved.

    本发明公开了一种基于递归图分析的列车稳定性评估方法,分别采集列车转向架左前侧车轮的、右前侧车轮、左后侧车轮、右后侧车轮的M个采样周期的振动加速度信号序列,将左前侧车轮的振动加速度信号序列视为振动加速度在三维相空间中的状态轨迹,根据任意两个采样时间ti、tj所对应的振动加速度向量在相空间中的距离与于临界距离的比较,构建左前侧车轮的M个采样周期所对应的M个递归图,根据任意相邻的两个采样周期的递归图的变化特征值,判断左前侧车轮的运行状态,类推得到转向架其他车轮的运行状态,进而判断判定列车的运行状态。本发明利用构建递归图对列车的稳定性进行判断,实现了对列车运行状况更全面和更精准的控制。
